APPARATUS FOR MARKING SIGN-PAINTER? CLOTH.

Application filed April-13,

' To all whom it-mag concern:

7 Be it known that I, HOWELL E. GRAHAM,-

the marking of sign painters cloth in such manner as to provide a cloth having sufiiciently visible lines provided thereon to avoid the necessity of the sign painter laying out the lines on the cloth lettering or painting the sign.

Heretofore it has been sought in many ways to furnish sign painters with cloth with suitably spaced longitudinal lines but no practical method orapparatus has been as yet devised for marking the lines in such manner" that they would serve theirpurpose and yet be so easily removed after the work was completed that they would not 1n any manner deface or detract from the appearance of the finished sign.

I have conceived the idea that these lines can be practically and successfully laid on the cloth by dredging lines of coloring matter thereon, the coloring matter being laid on so lightly that it can be dusted off after 7 the completion of the sign and which yet leaves marks sufliciently durable and visible to enable the cloth to be preliminarily marked, then bolted and later torn off to lengths.

7 My present invention is concerned more particularly with the apparatus which I consider best suited by dredging action for applying these marking lines to the-cloth. In its preferred embodiment, it comprises a drum containing colored material such as charcoal and provided with suitably spaced circumferential slots covered with wire gauze or the like through which the coloring matter is applied with a dredging action to the cloth passing around the drum. It will be understoodhowever that lclaim as my invention the utilizationvof an appropriate means'for applying the marks by dredging action to the cloth.

' My invention further, comprises thenovel details'of construction and arrangements of parts illustrated in the accompanying drawings, described indetail in the specification following, and pomted out in the appended preparatory to 1922. Serial No. 552,298.

claims, it being understood that the detail construction shown may be widely modified to meet varying operating conditions withoutdeparting from the substance of my invention.

According to the drawings Fig. l is a-perspective view of a marking apparatus showing a strip of sign painters cloth being passed around. the same and marked thereby, all supporting bearings being omitted.

Fig. 5 illustrates a modified type of stay and brake plate for thedrum sections.

r Similar reference numerals refer to similar parts throughout the drawings.

In the embodiment illustrated, I show a strip of sign painters cloth 1 passed over a guide roller 2 and about a marking drum 3, and then about second guide roller 4 whence the marked cloth passes to use or to be rewound in a bolt. These guide rollers 2 and 4 are mounted in bearings 5 at the top ofthe side frames 6. These frames are adapted to be bolted or attached to the floor and are provided with vertically elongated slots 7 which receive a center shaft 8 pass-- ing through the drum 3 and suitably keyed in bosses 9 on metallic heads 10 of the drum. The bearings 5 are carried by vertical extensions at each side of each frame 6, the top of the frame between the extensions coming below a filling ..door 11 in either or 7 both heads 10 when such doors are moved to their uppermost position. By this means the drum can be suitably charged with charcoal or other material which, when abraded by the rolling action in thedrum, will furnish the marking material which will be applied by dredging action to the cloth 1 by means which will now be described.

7 The drum is formed with a series of spaced circumferential slots 12, these slots being preferably continuous and provided by forming the-drum; of a series of cylindrical imperforate sections 13 which are con- 110 nected together along their adjacent edges by strips of wire gauze or hardware clothlt suitably soldered or secured to the cylinders 13. To further brace the cylindrical sections 13 together without interrupting the continuity of the slots 12, I provide the drum with any desired number of stay strips formed by a metal strip 15 bent in fluted form, as shown more clearly in Fig. 3. The bases 16 of the fiutes or arches are arranged to engage the cylinders 13 near their centers and to be brazed or soldered thereto, the stay plate, by means of its arches projecting into the drum, forms breaking or abrading projections which engage the charcoal or marking material therein and cause its disintegration to furnish the cloth marking material. The roughened surface of the woven wire or hardware cloth 14: also serves to abrade the marking material. Though I have shown only two of these connecting stay plates 15 in the drawings, it is to be understood that any desired number of such plates ma" be employed as various operating conditions may find necessary.

In operation, having charged the drum with charcoal or like marking material, the fabric to be marked is passed over the roller 2 and around the drum and over the roller 4 and drawn taut, so that the drum 3 is supported in the bite of the fabric and is rotated thereby as the fabric is drawn out. This results in the drum being rotated as the cloth is drawn and as it rotates the abraded marking material is deposited or dredged I through the annular slots 12 and is laid in stripes or marking lines upon the cloth. It is to be noted that there is no scraping or rubbing action between the drum and the cloth as the two turn together, and after the V dusted oil the cloth leaving it unmarked.

As a means for further increasing the usefulness of this marking appliance, I design it tohave a circumference equal to a standard unlt of measure, preferably one yard, and I provide lengthwise of the drum a series of small holes 17 which will place on the cloth between the'longitudinal lines at every yard interval a series oi dots 18 which mark the finished strip to indicate yard lengths.

In Fig. 5 I show a modified stay formed by a metal bar 19 notched along one edge to bridge the slots 12 and being suitably soldered or welded along its notched edge to the drum sections 13. This affords a better means for breaking up the charcoal. I preier to leave the slots 1.2 uninterrupted but ohviously the brace plates may interrupt same for such short intervals as will not affect the serviceability of the resultant lines.

I have not claimed in this application the marked sign painters cloth as an article of manufactm'e, as the same forms the subject matter of a pending application of even date herewith, Serial No. 552,299.

Though I have described with great particularity the details oi the embodiment of theinvention herein shown, it is not to be construed that I am limited thereto, as
